MESHED W IRE FOR WIRE-GLASS MANUFACTURE.

SPECIFICATION forming part of Letters Patent No. 727,004, dated May 5, 1903.

Application filed June14, 1902. Serial No. 111,744. (No model.)

To all whom it may concern:

Be it known that we, FRANK SHUMAN and ARNO SHUMAN, of the city and con nty of Philadelphia, State of Pennsylvania,have invented an Improvement in Meshed Wire for Wire- Glass Manufacture, of which the following is a specification.

Our invention has reference to meshed wire for wire-glass manufacture; and it consists of certain improvements fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of our invention is to provide a r 5 construction of meshed wire in which the twisted portions are in substantially one plane and the connecting portions bent or curved so as to project laterally or outward from said plane as a base, the said bent porac tions providinga series of supports especially sensitive to stretching tendencies when heated'namely,those tendencies which come into play in the manufacture of wire-glass.

Our invention will be better understood by reference to the accompanying drawings, in

which Figure 1 is a plan view of a-portion of meshed wire embodying our invention. Fig. 2 is a longitudinal sectional elevation ofsame on line 2 2 of Fig. 1. Fig. 3 is a cross-section of same on line 8 3 of Fig. 1, and Fig. 4:" is a perspective view of a modified form of one of the twisted portions.

The meshed wire is made up of a series of wires A, twisted together at intervals, as at B and B, said parts being connected by diagonal portions of single untwisted wires 0. In the preferred form the wires form hexagonal structures and apertures, as shown in Fig. 1; but we do not limit ourselves to any special shape in thisjrespect; The twisted-wire portions B B"lie in one plane, and the connecting portions 0 are in part or in whole bent or curved laterally or away from the plane through the twisted portions. The portions 0 are preferably all bent to one side, as shown in solid lines in Fig. 2, or a portion may be bent to the other side of the twisted portions,

as indicated in dotted lines, which may represent the wires O. beyond the most forward ones'that is to say, in the same structure a portion of the parts C may be.bent in 'one direction and a portion 0' in the other direction. The bent portions '0 act as supports for holding the meshed wire in position during the operation of applying the molten glass.

and are made ductile; so as to be easily stretched and more or less straightened during the glass-making process. As it is desirable to give rigidity to the twisted joints of the wires at B B, they may be flattened or compressed at these places, as indicated in Fig. 4.

It is immaterial to our invention, generically considered, how the meshed-metal structure may be formed, provided that the parts corresponding to the portions B B are substantially in one plane and the connecting diagonal parts'are bent or curved away from such plane, and hence we do not wish to limit ourselves to a round wire by use of the term meshed wire. Any suitable form of metal strand may be used.

When stating that the twisted portions B B of the meshed wire lie in one plane, we do not intend to restrict ourselves to a mathematical nicety in this regard, but wish to be understood as meaning that the location of these twisted wire or united portions of the wire are arranged in substantially the same plane or layer and irrespective of whether the said portions are perfectly straight or not., While we prefer the parts B B to be straight, nevertheless in practice they are more or less irregular and may, if desired, be somewhat curved, as at D in Fig. 2, without departing from the spirit of our invention, both as described and claimed.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A meshed-metal layer for wireglass manufacture consisting of a series of metal strands twisted together at intervals to form an open mesh and in which the connecting untwisted strands at close intervalsare bent away from a plane through the twisted strand portions and to a distance considerably to one side of them whereby they are supported clear of a plane through the bends of the bent portions.

2. A meshed-wire layer for wire-glass consisting of an open or meshed structure of wire the apertures of which are composed of a series of parallel straight portions in one plane connected by diagonal portions, and in which the said diagonal portions are bent with a single deep bend so as to extend laterally away from the plane of the parallel straight portions and to a distance considerably to one side of them whereby they are supported clear of a plane through the bends of the bent portions.

3. A meshed-wire layer for wire-glass consisting of an open-meshed structure of wire the apertures of which are composed of a series of parallel straight portions in one plane connected by diagonal portions, and in which the said diagonal portions are bent so as to extend laterally away from and above and below the plane of the parallel straight portions and in which the distance between the planes of the upper and lower bends is made much greater than the thickness of the straight portions.

4. A meshed-wire layer for wire-glass manufacture consisting of a series of wire strands twisted together at intervals to form an open mesh and the twisted parts flattened to make rigid, and in which the connecting untwisted wires at close intervals are bent away from a plane through the twisted-wire portions.

5. A meshed-metal layer for wire-glass manufacture consisting of a metal structure of open or meshed form having a series of por-
